Japan's Nikkei 225 index tumbled more than 3% on Friday, marking a sharp deterioration in Asian market sentiment.
The decline was driven by a dual shock: a broad-based global rout in chipmakers and intensifying geopolitical tensions in the Middle East involving Iran.
Investors moved decisively away from risk assets as uncertainty mounted.
The selling pressure was particularly acute in the technology sector, where semiconductor-related equities faced heavy liquidation.
This tech-led weakness weighed heavily on the broader index, dragging down performance across multiple sectors.
The move reflects a broader repricing of risk as traders assess the potential economic fallout from both supply chain disruptions and geopolitical instability.
